How does the Op Amp Gain Calculator work?

Inverting: gain = -Rf ÷ Rin Then: Non-inverting: gain = 1 + (Rf ÷ Rin) Then: Bandwidth = gain-bandwidth product ÷ gain Then: Input impedance affects signal source loading.

Can you give an example of how to use the Op Amp Gain Calculator?

Example: Input Rf=10k, Ri=1k gives a result of Gain = -10.

Is the Op Amp Gain Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
